810 nm high power LED, also known as the 810nm high power laser diode, has become a hot topic in the optoelectronic industry. As a new generation of semiconductor light-emitting devices, it has been widely used in medical, military, industrial, and other fields. This article will introduce the 810 nm high power LED, including its basic principles, characteristics, application fields, and market prospects.

Basic Principles of 810 nm High Power LED

The 810 nm high power LED is a semiconductor device that emits light through the recombination of electrons and holes in the material. The basic principle is based on the photoelectric effect, which is the interaction between light and matter. When the electrons and holes in the semiconductor material are recombined, a certain amount of energy is released, which is converted into light energy. The 810 nm high power LED uses a semiconductor material with a bandgap of 1.23eV, which corresponds to the 810 nm wavelength of light.

Characteristics of 810 nm High Power LED

1. High power output: The 810 nm high power LED has a high power output, which can reach up to 10W.
